Yeah, iv had a similar idea, but were actually going to do it. My friends got a 93 Si hatch and were swapping out the d16 into a shifter kart and hes building another motor to swap (maybe b16-t). the frame going to need some extending but its basically the same idea as yours...aside from the frame size. Ill keep you posted on what we do with the shif linkage, etc, because we want to use the clutch, and shift setup as if it were in a car.
